My friend is a bit paranoid, she took althea pills (21 tabs).. She told me, it s her 1st time to take the pills. Within the first 7days, she had an unprotected sex.. The tablets were taken regularly though, and now, she is on her 7th day of the 7day tablet free but she hasn t had her cycle yet.. She s worried if she s pregnant. Is there something that she should worry about?
